Dimensionless design of variable displacement pumps

Research output: Chapter in Book/Report/Conference proceedingConference contribution


External market forces constrain the design of engineered systems in much the same way that environmental conditions constrain the evolution of biological systems. Dimensional analysis is used to find functional relationships within biological systems and in turn can be used determine design relationships for engineered ones. This work applies these concepts to axial-piston swashplate variable displacement pumps. After presenting a pump model suitable for dimensional analysis, the necessary transformations are performed to create a pump model with completely dimensionless parameters and dynamics. Using a set of industry data, scale independent design information is extracted from successful industry pumps. This information is used to develop dimensionless design guidelines and strategies which allow for the specification of new designs dynamically similar to the original successful products.
